Overview:

The CURTIS 1230 motor controller is an AC induction motor speed controller designed for use in a variety of material handling vehicles. Typical applications include walkie/rider pallet trucks, low lifts, stackers, sweeper/scrubber machines, and other small industrial vehicles. This high performance programmable controller is simple to install, efficient, and cost effective.

The 1230 controller offers smooth precise control of motor speed and torque. When used with hydraulic systems, the 1230 turns the pump motor on and off and also controls valves on the hydraulic line—thus controlling the hydraulic path for Lift and Lower operations. These controllers are fully programmable through the CURTIS Model 1313-4401 Handheld Programmer or 1314 PC Programming Station. The programmer provides diagnostic and test capability in addition to configuration flexibility. The 1230 is also designed to work with the optional CURTIS 840 Spyglass data display and the optional CURTIS 1312 tiller multiplexer.

Features Include:

• 60–200 amp AC induction motor controller
• MultiMode™ feature allows two distinct user-selectable operation modes
• Easily programmable through the CURTIS Model 1313-4401 Handheld Programmer or 1314 PC Programming Station
• Complete diagnostics through the programming devices and through the controller’s built-in Status LED
• Throttle input for single-ended or wigwag 5kΩ pots or 0–5V throttles (both standard full stroke and restricted range)
• Active precharge of controller capacitor bank extends life of main contactor tips
• Two hourmeters - total KSI-on hours and drive hours - and their associated maintenance timers are built into the controller, with EEPROM storage (no battery)
• BDI calculations performed within controller
• Meets EEC fault detection requirements
• Fault detection circuitry on throttle inputs can be used to inhibit operation if throttle signal goes out of range for any reason (applies both to the traction throttle and, in applications that include a proportional valve, to the hydraulic throttle as well)
